Actually, I think it's necessary. After all, mathematics is a big subject in high school. If you study science, mathematics can be said to be the foundation. If completed, mathematics is the top among liberal arts, but mathematics accounts for 1/4 of the world.

Senior three is an important stage, especially the next semester, which is a very good opportunity for you to check and fill in the gaps in winter and summer vacations. After all, after a round of review, you will miss the math before filling in the gaps. Only by constantly enriching yourself can we make continuous progress.

Here, we should observe ourselves carefully. When we were studying mathematics at that time, what didn't we learn well and what did we learn well? When I reviewed last semester in Grade Three, I didn't review well, but I reviewed well. So this is very important, so we must be careful.
